I shut it down and removed the Windows to Go media. It rebooted and flashed the new BIOS version during boot successfully. Surprisingly, the flashing program is not signed, so you have to accept that the vendor is not recognized, so you pass the Smart Screen block. It did not recognize any other USB flash drives, where I placed the BIOS update, and did not recognize a USB Ethernet adapter, so I had to connect to Wi-Fi and download the update from the official Acer website. It displayed some minor errors here and there. The Windows setup turned out to be buggy. Probably, will try a faster device, like an external HDD, next time. A newer USB 3.0 flash drive succeeded to boot, but Windows was very slow. I tried to use an older USB 2.0 flash drive, but it did not boot to Windows setup in hours. It took hours to create the bootable USB and more hours for Windows first boot and setup. Had to change the boot sequence in BIOS to boot from this media. Had to choose Windows to Go option instead of the usual installer option in Rufus interface. Unfortunately, Windows to Go is no more officially supported by Microsoft, but I created one with Rufus with an official Windows 10 installation image, which is freely available to download from the Microsoft website. Please be warned that this option does not seem to be safe and reliable.
$ echo `sudo dmidecode -string baseboard-manufacturer` `sudo dmidecode -string baseboard-product-name` `sudo dmidecode -string baseboard-version`Įdit: The flashing tool which is included into the update is Insyde H20FFT (Flash Firmware Tool) version 2.00.11.00 from Insyde Software Corp.Īs Tony suggested, I tried "live" Windows to update the BIOS firmware. Is there a way to update BIOS other than installing Windows over my currently installed Debian? $ echo `sudo dmidecode -string bios-vendor` `sudo dmidecode -string bios-version` There seems to be no option to update BIOS in BIOS itself. Unfortunately, the laptop does not pick up it from the USB flash drive on boot. Among all files there is a "abobios.bin", which seems promising. I opened the executable with fileroller and extracted all files from it onto an empty FAT32-formatted flash drive.
Installing Windows seems like too much work to update BIOS. The download from the website is a zip archive, which contains an executable and a README.txt, which instructs to click the executable under Windows. The official website has a new version of BIOS for my laptop.
